First of all Bro, how long have you been on HGH??
It takes over 6 months before you really start to notice anything.

Second of all, the cream isn't really going to accomplish much....you might want to think of ditching it when you are trying to build mass and get some real gear.
After all, you are already on steroids ;)

Testosterone cream is just Testosterone base...there are no esters attached....thats just for injectables.

You need to up your protein.....100g wont cut it if you are trying to gain muscles....drink a couple of more shakes (definitely pre and post workout and before bed). Get some protein bars and have a couple a day - 20 plus grams of protein preserving (thats an extra 115g between the shakes and bars).

Besides that, from what you are saying, I would say that you are over training.

Now if you want to give me 4 to 6 weeks of your time....follow the workout, diet, and supplements.....i could do amazing things for you! ;)
